If you can't beat 'em, join 'em... The moon is so bright I can read a book in my front yard at midnight! So, I took its picture. I can't get it all in the 250P, so I used the guide scope. This is 1 shot at .001 seconds using a Svbony SV305 camera and a Svbony SV106 60mm guide scope and some light touch-up (mostly cropping) with GIMP.

Nice job! Andromeda Galaxy is a good be this time of year (M31). There are also a lot of other targets around M42, but they are a bit dim and harder to find. Right now the moon is near full, so that makes things tedious. in a couple of weeks it gets easier once again.

I got a surprise last evening. The moon was making dim objects a bit tedious, so I started "collecting" Messier open clusters. I really don't like open clusters as a rule, but conditions make limits. In the midst of a quick peek at M-46 I found a smudge. It wasn't dust or a cloud, so I looked further. It was a nice little planetary nebula hiding in the cluster. Imagine that! NGC-2438 inside M-46 (100 - 20 second images stacked with Siril and processed with GIMP).

@BCN_Sean: Nope, got that right. I'm an old-school terminal kinda guy. cd is my friend. The only thing I drag is my feet. @JamesF: Yep, no avx support. I knew it smelled like a library issue. Odd that -none- of my hardware has it. Still, I don't generally buy hardware with an eye for graphics support.

JonCarleton started following StarNet++ Will Not Run on ANY of my Linux (AMD64) Systems
-
I downloaded from SourceForge the StarNet++ Linux tar.gz file onto a few Linux Ubuntu laptops and desktops (all AMD64 processors) I have and crashed and burned with every attempt. I am running Ubuntu 20.04 on most of them, but I did try on a 19.x version for grins (also a fail). When I untar/zip the file and run the test shell script, I get a core dump. For that matter, I get a core dump if just try to run the executable. I am not running PixInsight and just want to run the program stand-alone. If I must, I'll load some other version of Linux on a machine to make it happen. Anyone ha

@Bright Giant: Probably I just fat-fingered something and created a second post. Ended up with two and couldn't delete the second one...which was originally the first with the wrong image.
-
Apparently, one cannot delete a bad image upload.

M81 Bode's Galaxy - 180 subs @ 15 seconds, stacked with Siril, processed with StarTools.
-
M82 - Cigar Galaxy, 200 subs @ 15 seconds stacked with Siril and processed with StarTools (although I did a quick-and-dirty test process with GIMP that resulted in an image that wasn't significantly different from this one). I am very disappointed that I got no hint of the nebular flare that is supposed to extend above and below the galactic center. Apparently, I need many more subs to get that feature. A shame, as I would be reasonably pleased with this image if I didn't know about the nebula I failed to capture.
-
M1 - Crab Nebula 130 10-second subs stacked with Siril and processed with StarTools. Alas, yes. I know I still have squishy stars. Auto-focus works, but guiding doesn't. PHD2 seems to hate my mount...not really designed for Alt/Az, I suppose.
-
We had a good night of seeing conditions, so I got some distant targets, Cleopatra's Eye Nebula and Superman Galaxy. Stacked 100 subs @ 20 seconds for each image.

I have never used the SV105 for guiding, but the SV305 is my guide camera now. It has worked without fail with the indi_sv305_ccd driver for indiserver. I have used it to image in the past and occasionally now through the guide camera with exposure up to 30 seconds. I typically guide with an exposure of 2-3 seconds. There may have been some issues with the driver when it first came out that artificially limited the camera for ASCOM or INDI, but I know that, for INDI, at least, that was corrected at least 8 months ago. There have been some minor issues with the SV305Pro (not related to expo
